NIR spectrometers are the new generation of Fourier Transform near Infrared (FT-NIR) spectrometer. These are the first industry hardened FT-NIR systems that are strong enough to withstand the harsh conditions.
NIR spectrometer uses the state-of-the-art optics for exceptional sensitivity and stability. There is continuous improvement in the designs and this provides consistent high quality results with less downtime, direct methods transfer and probable new applications. These NIR instruments can be used both in the lab and the factory; thus eliminating the need for new instrument during integration with the process control system.
In addition, the same NIR instrument can go directly from the lab to the factory, and this removes the need for a new instrument when your method is ready for integration into your process control system. These can further be integrated easily because of the Full support of industry standard communication protocols available.
The most successful NIR instrument is the Raman spectrometer which was developed for process control and automated lab applications. The system emphasize an On-Axis spectrograph, optimized for Raman spectroscopy and one standard grating covering the most widely used Raman signature range. The patent pending curve slit correction for aberration free imaging, low noise CCD and innovative technology in signal processing result in excellent signal to noise ratio and high performance.
Many NIR instrument come with no moving parts, being free from mechanical wear it requires low maintenance. The integrated diode laser provides 532 nm or 785 nm with different power levels available.
The system comes equipped with a Class 3 light-tight safety enclosed with interlocks in 19" rack
configuration.
The NIR spectrometer has taken NIR spectroscopy to new heights and is compatible for a choice of laboratory, site glass and process immersion probes, allowing real time process monitoring from a remote location. The Raman UniLab Research is a high sensitivity device designed to utilize both large illumination and collection areas. The large illumination design reduces the susceptibility of sample misalignment as well as decreases the effects of heterogeneity issues of the sample, resulting in superior averaging capability.
NIR spectroscopy utilizes Sure_Cal calibration technology, a method for achieving a standard Raman spectrum that has both short and long term precision and accuracy. The Sure_Cal technology allows for the collection of the standard spectrum independent of any instrument instabilities. The Raman spectrum from the sample, the laser/neon spectrum and the neon spectrum are collected simultaneously.
The NIR instruments are also much easier to implement, operate, and maintain. The NIR spectrometer is a compact fibered spectrometer able to measure from 900nm to 2600nm or from 2000nm to 4500nm with a resolution of 8cm-1 (or about 1-5 nm). This world known unique scanning Fourier Transform Spectrometer (FTS) uses an exclusive actuator fabricated thanks to modern micro machining technology. The spectrometer needs only a single detector that assures highest dynamic range and allows attractive pricing.
